The safest way for you to be find a job in Australia after your studies is to select a course that allows you at completion, to be eligible for a work visa in Australia. With the help of migration agents, we have identified which qualifications would allow you to be qualified and work in your professional field without much struggle.
The clearest one is to complete at least 2-year University studies to be eligible to the Post Study Work Visa - Subclass 485, at Bachelor or Master degree level. We can guide you through this process. This option requires to have an excellent level of English and financial evidence to cover the high university fees (minimum AU$20,000/year).
Some vocational training courses up to 2 years and from AU$8,000/year allow you to apply directly to some work visas (TRV or Permanent Skilled Migration visas).
